Abstract
The utility model relates to a cornea that has the horizontal location appearance includes position mark ware ring, calibrated scale, level device, handle along the accurate positioner of astigmatism, this cornea along the accurate positioner of astigmatism, is equipped with the calibrated scale on the position mark ware encircles, and the calibrated scale is inside to be equipped with 0 -360 degree scale for the cavity circle on the calibrated scale, and main scale has digital identifier, and calibrated scale lower edge, handle top are provided with the level device. It is accurate that this cornea is fixed a position along astigmatic positioner, and the level device helps the accuracy of eyeball horizontal location mark, is convenient for operate in the operation, improves the accuracy nature that the cornea was fixed a position in performing the operation along the scale.
Description
Technical field
This utility model relates to ophthalmic medical field, specifically relates to a kind of limbus of corneae astigmatism accurate positioning device with level indicator.
Background technology
Existing limbus of corneae marker is the toroidal of rule, and marker upper surface is the plane after polishing, and indicates circular scale.V-type opening is offered in the position of 0 degree and 180 degree, as labelling reference coordinates, is furnished with fixation mark ring in single handle Rhizoma Atractylodis Macrocephalae, to level marks entirely with operator's subjective sensation, often cause 0 degree and 180 scale designations deviation in various degree, and then the deviation causing subsequent corneal edge astigmatism to locate, affect the postoperative effect of ophthalmologic operation more or less.
Utilizing marker positioning operation position when needing patient to be in seat in operation, because hand-held marker is easy to occur change in location, occurring surgical errors as located inaccurate being easy to, cause operative failure or surgical effect poor.Therefore, need accurately to locate the position of marker.
For overcoming above-mentioned defect, need the limbus of corneae astigmatism positioner designing a kind of accurate accurate positioning.
Utility model content
The purpose of this utility model is for above-mentioned deficiency of the prior art, by providing a kind of limbus of corneae astigmatism positioner, to improve operation technique convenience, accuracy.
In order to solve the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of limbus of corneae astigmatism positioner, this limbus of corneae astigmatism positioner comprises telltale mark device ring, graduated disc, handle, this limbus of corneae astigmatism positioner also comprises horizontal device, telltale mark device ring is provided with graduated disc, graduated disc is inner is hollow circle, graduated disc is provided with 0-360 degree scale, is provided with horizontal device above graduated disc lower edge, handle.
This horizontal device is level indicator, level indicator inside is provided with a transportable bubble, when bubble is positioned at level indicator centre position, represents this limbus of corneae astigmatism positioner maintenance level, namely 0 degree, 180 degree are positioned on same level line, and horizontal device contributes to the accurate of eyeball horizontal location labelling.
A V-arrangement angle is formed between the telltale mark device ring of handle and handle upper portion, graduated disc.
This angle is 150 degree.In graduated disc, hollow circular diameter is 12mm.
Compared with prior art, this utility model has following technique effect: this limbus of corneae astigmatism positioner accurate positioning, and horizontal device contributes to the accurate of eyeball horizontal location labelling, is convenient to operation in operation, improves the accuracy of limbus of corneae scale location in operation.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model limbus of corneae astigmatism positioner.
Fig. 2 is the side view of this utility model limbus of corneae astigmatism positioner.
Wherein, 1, telltale mark device ring; 2, graduated disc; 3, horizontal device; 4, handle.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further:
This limbus of corneae astigmatism positioner comprises telltale mark device ring 1, graduated disc 2, horizontal device 3, handle 4, telltale mark device ring 1 is provided with graduated disc 2, graduated disc 2 is inner is hollow circle, its interior diameter is 12mm, graduated disc 2 is provided with 0-360 degree scale, major division has Digital ID, below graduated disc 2, horizontal device 3 is provided with above handle 4, horizontal device 3 is level indicator, level indicator inside is provided with a transportable bubble, level indicator is provided with scale, when bubble is positioned at level indicator centre position, represent this limbus of corneae astigmatism positioner maintenance level, namely 0 degree, 180 degree are positioned on same level line, horizontal device contributes to the accurate of eyeball horizontal location labelling.
For the ease of operation, the part of handle and handle upper portion forms a α angle, this angle preferably 150 degree.
This limbus of corneae astigmatism positioner is located for the circumferential angle of cornea, and be mainly used in astigmatism location, level indicator is the registration in order to ensure trunnion axis.During use, telltale mark device ring is directly buckled in the cornea edge of seat patient, observes limbus of corneae astigmatism positioner whether level by horizontal device, first carry out 0 degree, 180 scale designations, then carry out the further labelling of required angle.
Above embodiment only for illustration of this utility model, but not to restriction of the present utility model.Although be described in detail this utility model with reference to embodiment, those of ordinary skill in the art is to be understood that, various combination, amendment or equivalent replacement are carried out to the technical solution of the utility model, do not depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
